1 Teacher Guide Bird Migration and Climate Change Developed by: Mark Koschmann Activity Focus: Major Concepts: Global warming may be affecting bird migration. Objectives: After completing this activity, students will be able to: explain how greenhouse gases may be affecting global temperatures. explain how the green house effect works explain factors that may determine bird migration determine robin migration pattern with temperature patterns predict how global warming may affect future robin migration Materials and Preparation: You will need to prepare the following materials before conducting this activity. Copy the Bird Migration and Climate Change (make 1 copy per student). May be helpful to have a color copy for each group. Make a transparency or PowerPoint slide for each map and figure. Procedures: Students may work individually or as a group to complete the remaining aspects of the activity. 1. Introduce the activity by asking students to identify some of the factors that influence bird migration. How would climate change affect bird migration? Read the Engage Your Thinking introduction and have the students answer the questions before starting the next section. You may want to discuss these as a class. 2. In the Explore and Explain section, the first part looks at climate change, greenhouse gases, greenhouse effect, and global warming. Students, in small groups, will read and answer questions. The second part focuses on bird migration, the factors that cause migration and how migration may be changing. Students will need to look at robin migration maps and draw a line of best fit (separating half of the sighting to the south and half to the north). Isotherm maps are provided after the robins migration maps to see if there is any correlation between the two. The third part of this section explores the difference between long distance and short distance migrants and how climate change may affect these migrants.

2 An optional activity (Migration Headache adapted from Project Wild) is to play a migration game to help explain the distance migration and climate change Project Wild: Migration Headache (or should we say Climate Change Headache?) Objective: Students will understand how global warming may affect different migrants as they compete for nesting sites (cavity nesters). Class Size:20 students Materials: 2 hoola hoops, 4 plastic gym spots (adjust numbers according to class size), gym or large area outside Have 6 students be the long distance migrants; they start their migration at out of bounds line in gym (under basketball rim) Have 6 students be the short distance migrants; they will start their migration at the free throw line closest to long distance migrants Place 4 hoola hoops with 2 plastic spots in each (Hoola Hoops are the trees and the spots are the cavities) Hoops are placed on opposite end of the gym. Others in class stand on the sidelines and the will become chicks after the migrations. Migrate to other end. Put foot on the spot (cavity). Must have 2 birds of the same species on the spot to successfully breed. Those that are successful may now pick 1 chick. Rules: 1. Must walk!! (this is not a hockey game) 2. Must mate with same species Steps: 1. Practice migration 2. Allow LDM (long-distance migrants) to migrate first by saying flycatchers migrate. Then allow SDM (short-distance migrants) to migrate by saying starlings migrate when the LDM arrive at the free throw line where the SDM are starting at (they should arrive at their nesting sites at the same time). Record your results (graph- number of birds and year when done). 3. Repeat step 2, 2 more times. Record the results (3 years worth of data) 4. Repeat step 2 but allow the SDM to leave when the LDM are halfway to the free throw line (the SDMs should arrive at the nesting sites sooner than the LCMS). Record your results (graph- number of birds and year when done). 5. Repeat step 4, 2 more times (if you have a population of LDM. If not game over). Record results (3 years worth of data) 6. If you still have a LDM population, repeat step 2 but this time let the SDM and LDM migrate at the same time. Record your results. (3 years worth of data) Graph and discuss the game. 1. What did the hula hoops and gym spots represent? 2. Which migrants, the short-distance or long-distance migrants had the nest cavity advantage? 3. What caused the advantage in the game? 4. What does Migration Headache game have to do with global warming? Activities for Conceptualizing Climate and Climate Change 2

3 3. In the Extend Your Thinking students will construct a concept map using the terminology reflected in the previous section. 4. Apply What You Learned has a map of North America and the students will draw a line of best fit for the year In the Reflect What You Learned answer the questions and see if there are any changes in your answers. 5. Administer assessment item. 6. Optional Assessment: Look up a species of migrating bird (example: red winged bird, oriole, etc ) and write a brief summary of how climate change may be affecting the species. Assessments: The following assessments may be used as a pre/post activity assessment or as part of a module assessment. How do greenhouse gases affect the greenhouse effect? How does the greenhouse effect affect global temperatures? What factors determine bird migration? How would climate change affect the migration of birds? Quiz: The following quiz may be used as a post activity assessment. How do greenhouse gases affect global temperatures? How does global warming affect bird migration? Robin migration seems to be mostly influenced by: A. Open water B. Day Length C. Temperatures D. Changes in habitat The global warming may be affecting the short and long distance migrants by: A. Both the long distance and short distance migrants are arriving at their nest areas at the same time B. The long distance migrants are arriving at their nesting areas before the short distance migrants C. Both the long distance and short distance migrants are arriving earlier to their summer nesting areas. Activities for Conceptualizing Climate and Climate Change 3
